@no2rbo,
There must be some organizations you could contact that could provide a foster home for him for a while. Our city has at least one that helps with food and shelter for animals of single people who are going into hospital or hospice. Call your humane society and ask what they are. You should be able to visit your dog, as well.
Also, you could post on your NextDoor, FB, etc., apps that you have a dog and are looking for a place. When I was a landlady, my tenants could have all the animals they wanted - homes are always better with an animal in them. Even if you rented a room in a house, many owners would love to have a dog they didn't have to walk and feed
I love how you love your dog
